Definitions

  • the invention relates to a sliding joint for a two-part tool according to the preamble of claim 1.
  • Such tools are in particular pliers, for example water pump pliers, of which two main types are common, namely a relatively simple one Version with on-hook joint and a more elaborate version with pushed through Joint. Common to both types is that a contoured slot guide a stepwise adjustment to a desired range allowed.
  • the legs are like a pair of scissors by means of a Bolzens connected, usually bolted to a joint.
  • a Bolzens connected usually bolted to a joint.
  • the object of the invention is to provide a simple sliding joint, especially for Pliers of the launched type is suitable.
  • the slip joint should be like plugged Knopfrastzangen a locking and unlocking at the touch of a button allow, but at at least equivalent function require less manufacturing effort.
  • Another one The goal is to use the slip joint for use with pliers including water pump pliers so that they form directly on the workpiece and always set parallel jaws quickly and safely, without any unwanted Adjustment would be possible.
  • the new slip joint for a two-part tool consisting of the following functionally connected components: a slider, a locking pin, a bush, a compression spring and a Pushbutton.
  • the compression spring and the push button can also be a common Form component. The small number of components allows a clear overview Construction and very favorable usage characteristics. Therefore, the slip joint is at a Variety of tools used.
  • the slider preferably has a guide flange which can be moved along a tool part and has a step body which is flattened on two sides and has a central blind hole opening and, on the narrow sides of a projection facing away from the flange, an external thread.
  • the axially movable in the step body of the slider locking bolt has a shank and a particular widened cylindrical foot, which is rotatably seated in the blind hole of the slider. This one has a robust component of simple form and correspondingly high structural strength.
  • the bushing can be attached to a second tool part and has on a collar on a remote internal thread, which is screwed with the approach of the slider-stage body to stop.
  • the sleeve thus secures a predetermined distance and protects the surrounding parts of it.
  • a central bore in the bottom of the blind hole breakthrough leads the locking bolt shank which is connected at the end to the push button , in or with which the compression spring is supported, which has its counter bearing on the blind hole bottom and supports in each position a locking, which by Overcoming the spring force can be solved by pressing a button.
  • the illustrated slide joint 10 consists of a maximum of five components: a stepped Slider 12, a locking pin 14, an insert sleeve 16, a compression spring 18th and a push button 20, wherein compression spring and push button and a common Can form a component.
  • a pair of pliers the two legs or handle parts A, B with each other at a variable distance opposite (not drawn) gripping jaws, wherein a first handle part A a profiled slot L. and a second handle part B has a bearing bore or a round hole R, wherein the Sliding joint 10 is mounted.
  • the locking pin 14 ( Figures 4a, 4b) is axially displaceable in the slider 12 ( Figures 2a, 2b) guided by a cylindrical foot 15 of the locking bolt 14 in a centric Breakthrough 25 of the slider 12 is arranged freely rotatable.
  • a shaft 24 of the Locking bolt 14 is connected to the end of the push button 20. This is supported by the compression spring 18 at a breakthrough 25 axially limiting bridge 13 in Slider 12 from which forms the bottom of a blind hole 21.
  • the slider 12 has a guide flange 23 which can be moved along the slot part A. and a two-sided flattened step body 22 with an external thread 27 at a remote from the flange 23 approach 26.
  • the step body 22 performs the axially movable locking pin 14, whose widened cylindrical foot 15 in the Shank 24 passes, which rotatably seated in a blind hole 21 of the step body 22.
  • the insert 16 (FIG. 3 a, 3 b) is a bushing fixed to the round-hole leg B remote female thread 17, with the external thread 27 at the base 26 of the Step body 22 screws.
  • a central bore 30 in the bridge bottom 13 of the blind hole 21 leads the Locking pin shaft 24 which is connected at the end to the push button 20 (Fig. 5a, 5b), in which the compression spring 18 is supported, the counter-bearing at the bottom of the Step body blind hole 21 has.
  • Fig. 1a shows the sliding joint 10 in the locked position.
  • the foot 15 of the locking bolt 14 locked the slider 12 on the slot leg A and with the shaft 24 of the Locking bolt 14 connected push button 20 protrudes over the top of the insert sleeve 16 addition, which is fixed to the round hole leg B to stop.
  • the slip joint 10 is a very compact combination of a maximum of five components, the at one Two-part tool, namely a pair of pliers, is advantageously used to selectively a clutch in the desired position or a decoupling for changing to bring about the position.
  • the slider 12 has a slot L on a tool leg A along movable flange in the form of the shoulder 19 and a two-sided flattened step body 22, the approach 26 at the shoulder facing away Side has an external thread 27.
  • the shaft 24 of the locking bolt 14 together with its widened cylindrical foot 15 guided axially movable, namely rotatable in the centric Bore 30 of the blind hole 21, the bottom 13 an abutment for the compression spring 18th forms, which has its other support surface in or on the push button 20.
